Will bg 44k hurt my engine if i fill it with chevron gas that has techron already in it?

I routinely use gas from Shell (V Nitro) and Exxon premium. I even buy bottles of Techron in addition to what's already in the gas from the pump. They don't do much. Once I put in BG44k into the tank (and drive it for about one tank's worth of miles), I can feel the power in the engine come back. Feel, meaning, the car pushes you against the seat more when you floor it. Only BG44K does that.

Whats the difference between this and the fuel system cleaner?

Chris, I don't really have experience with other fuel system cleaners. I used BG44 on my engine builders recommendation. I was having problems with my racing engine building deposits on the valves and increasing leak-down percentage. With several cylinders showing 6 to 8 % leak down, I ran the next race with 1/2 can of BG-44 in 5 gallons of 110 octane rave gas. After the race, those cylinders were all below 2% leak down. Also the intake manifold runners were sparkling clean. I now repeat this process after 40 or so 1/4 mile runs and all cylinders are still between 2 and 3 % leak down.

2008 saturn astra with fuel filter in fuel pump-will it clean this filter?

Hi 44k is strong stuff and will clean and condition ALL parts of the fuel system. Filters included.

Is this necessary if i use top tier gasoline?

I use top tier fuels (always 93 octane), but I have read and studied American Society of Petroleum Engineers findings for years. With minor exceptions all cars from 1986 forward are electronically controlled by computerized fuel injection systems, and most recently direct injection systems that place the fuel delivery nozzles in close proximity to the combustion chambers. This creates a cleanliness hazard to the injectors. So, you can avoid a $150-$200 carbon depletion cure with 1 can of BG-44K every 5000 miles or less. Yes -- it is expensive, but if you look for sales and buy in bulk you can get it for half the retail price.

افضل منظف دائرة وقود كامل بالسوق

افضل منتج لتظيف دائرة الوقود كامل بدءا من خزان الوقود وانتهاء بدبة البيئة،بفضل انت تعرف مقاس خزان الوقود تبع سيارتك لان هذه العلبة تغطي حتى ٧٥ لتر بنزين من اجل الاستفادة كامله،كما يفضل عند إضافته لا تضيف اليه اي وقود من اجل ان لايقل تركيز المنتج..انصح به وبقوووة

Perfect product you will never find better

The best fuel system cleaner every company and brand will say that and it do more than it expects from fuel cleaner to do it clean all your car fuel system and even reach the exhaust system little bet, however I recommend using cataclean after it to clean the exhaust system So the way I use it bg with full tank then one full tank to clean the bg out of the system then cataclean added after driving for 30 min to increase the exhaust temperature then add cataclean with a full tank that the absolute cleaning your car can get

Check Engine (code P0430) will be cleared.

My 2004 Honda Accord has check engine w/ P0430 code (catalytic converter issue) and my mechanic recommended to put BG 44k. After 3 days, check engine went away. This is a true testimonial. I will use this every 10k miles. I saved money for not replacing catalytic converter.
